Fuchsia's undefined behavior sanitizer was detecting unaligned accesses
to 8 byte aligned data in Crashpad tests because various MINIDUMP_*
structs are packed with 4 byte alignment.
This change copies unaligned data in tests to local variable that can be
safely used to check values.
Example errors:
'''
[../../third_party/crashpad/minidump/minidump_thread_name_list_writer_test.cc:95:3]:
runtime error: reference binding to misaligned address 0x461e104cfbd4
for type 'const RVA64' (aka 'const unsigned long'), which requires 8
byte aligment
